### Convert Kubernetes objects to CUE
First, let's create re-usable definitions for the `deployment` and the `service` to remove a lot of boilerplate
and repetition.
First, let's create re-usable definitions for the `deployment` and the `service` to remove a lot of boilerplate and
repetition.
Let's define a re-usable `#Deployment` definition in `kube/deployment.cue`.
```cue title="todoapp/kube/deployment.cue"
package main
// Deployment template containing all the common boilerplate shared by
// deployments of this application.
#Deployment: {
// Name of the deployment. This will be used to label resources automatically
// and generate selectors.
name: string
// Container image.
image: string
// 80 is the default port.
port: *80 | int
// 1 is the default, but we allow any number.
replicas: *1 | int
// Deployment manifest. Uses the name, image, port and replicas above to
// generate the resource manifest.
manifest: {
apiVersion: "apps/v1"
kind: "Deployment"

containerPort: port

}
}
}
}
```cue file=tests/kube-kind/cue-manifest/deployment.cue title="todoapp/kube/deployment.cue"
```
Indeed, let's also define a re-usable `#Service` definition in `kube/service.cue`.
```cue title="todoapp/kube/service.cue"
package main
// Service template containing all the common boilerplate shared by
// services of this application.
#Service: {
// Name of the service. This will be used to label resources automatically
// and generate selector.
name: string
// NodePort is the default service type.
type: *"NodePort" | "LoadBalancer" | "ClusterIP" | "ExternalName"
// Ports where the service should listen
ports: [string]: number
// Service manifest. Uses the name, type and ports above to
// generate the resource manifest.
manifest: {
apiVersion: "v1"
kind: "Service"
metadata: {
"name": "\(name)-service"
labels: app: name

spec: {
"type": type

### Generate Kubernetes manifest

Create a new definition named `#AppManifest` that will generate the YAML in `kube/manifest.cue`.
